Brodsky, Jessica E.; Zomberg, Dvora; Powers, Kasey L.; Brooks, Patricia J. – Journal of Media Literacy Education, 2020
Internet users may fail to recognize how algorithms filter and personalize information. Two studies explored college students' algorithm awareness across varying contexts. Study 1 examined Facebook users' awareness of its algorithms (N = 222). Only about half recognized that Facebook does not show all their friends' posts. These students more…

Young, Lisa; Alfrey, Laura; O'Connor, Justen – European Physical Education Review, 2022
How physical literacy (PL) is presented on 'the web' (i.e. Google) has implications for how health and/ physical education (H/PE) teachers and coaches engage with and understand the concept, and ultimately how it is "made to" act in practice. This research sheds light on the type of PL content they are likely to encounter in their search…

Ham, Chris D. – Journal of Educational Research and Practice, 2019
Primarily due to their convenience, online search engines such as Google and Bing are becoming a central location for obtaining information. As a result, societies give search engines tremendous control over the spread of information to the public. Through a high-school-level sample lesson plan, the article was written to promote dialogue with…

Grady, Jonathan P. – ProQuest LLC, 2013
Social bookmarking systems allow people to create pointers to Web resources in a shared, Web-based environment. These services allow users to add free-text labels, or "tags", to their bookmarks as a way to organize resources for later recall. Ease-of-use, low cognitive barriers, and a lack of controlled vocabulary have allowed social…

Ding, Shuai – ProQuest LLC, 2013
The inverted index is the main data structure used by all the major search engines. Search engines build an inverted index on their collection to speed up query processing. As the size of the web grows, the length of the inverted list structures, which can easily grow to hundreds of MBs or even GBs for common terms (roughly linear in the size of…

Nagasinghe, Iranga – ProQuest LLC, 2010
This thesis investigates and develops a few acceleration techniques for the search engine algorithms used in PageRank and HITS computations. PageRank and HITS methods are two highly successful applications of modern Linear Algebra in computer science and engineering. They constitute the essential technologies accounted for the immense growth and…

Tsao, Nai-Lung; Kuo, Chin-Hwa; Wible, David; Hung, Tsung-Fu – Educational Technology & Society, 2009
In this paper, we propose a syntax-based text retrieval system for on-line language learning and use a fast regular expression search engine as its main component. Regular expression searches provide more scalable querying and search results than keyword-based searches. However, without a well-designed index scheme, the execution time of regular…

Romero, Cristobal; Ventura, Sebastian; Zafra, Amelia; de Bra, Paul – Computers & Education, 2009
Nowadays, the application of Web mining techniques in e-learning and Web-based adaptive educational systems is increasing exponentially. In this paper, we propose an advanced architecture for a personalization system to facilitate Web mining. A specific Web mining tool is developed and a recommender engine is integrated into the AHA! system in…

Pavlu, Virgil – ProQuest LLC, 2008
Today, search engines are embedded into all aspects of digital world: in addition to Internet search, all operating systems have integrated search engines that respond even as you type, even over the network, even on cell phones; therefore the importance of their efficacy and efficiency cannot be overstated. There are many open possibilities for…

Zhuang, Ziming – ProQuest LLC, 2009
The amount of online information has grown exponentially over the past few decades, and users become more and more dependent on ranking and recommendation systems to address their information seeking needs. The advance in information technologies has enabled users to provide feedback on the utilities of the underlying ranking and recommendation…

Oberdan, Thomas – Bulletin of Science, Technology & Society, 2009
The article "Is Google Making Us Stupid?" in last Summer's "Atlantic Monthly," raised a number of provocative, and indeed worrisome, questions about computer usage and cognitive development. For instance, persons with considerable experience of reading for the sake of pleasure report that, after a couple of years using computers a great deal, they…

Hu, Dawei; Chen, Wei; Zeng, Qingtian; Hao, Tianyong; Min, Feng; Wenyin, Liu – International Journal of Distance Education Technologies, 2008
A personalized e-learning framework based on a user-interactive question-answering (QA) system is proposed, in which a user-modeling approach is used to capture personal information of students and a personalized answer extraction algorithm is proposed for personalized automatic answering. In our approach, a topic ontology (or concept hierarchy)…

Junni, Paulina – Information Research: An International Electronic Journal, 2007
Introduction: The Internet has radically changed the global availability of scholarly publications. Today, a substantial part of the resources accessible for researchers and university students are offered through electronic site licenses, making the supply of easily obtainable information larger than ever. This brings forth an important question:…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
